I just got Kappa 60.5 components and 62.5i's to replace my stock speakers.

I'm planning on adding one 10" (or two 8's) in the stock location behind my seat.

I have a nice mtx one channel amp that would power the sub(s). My question is:

If I buy a 4 channel amp that has pre outs, can I power all 4 speakers with the amp (after converting the line), and then use the pre out RCA's to run to the sub amp?

Basically, it would look like this:



that took far too long to draw Thanks!

 

i just realized that there is no remote turn on for either of the amps in this situation... is there a way to wire that in to the car so the amps turn on when the car is turned on?

 

If the 4channel has RCA outs made for connecting to another amp then yes, you can do it that way. There is a remote-lead wire for every aftermarket headunit, I don't see why there wouldn't be one with the stock head.

 

is it safe to assume that the only reason an amp would have pre outs would be to go to another amp?

 

Generally speaking yes. Any pre-out on an amplifier is usually used to send the signal to another amp. This is done because some head units do not have three sets of pre-amp outputs which allows for individual right/left/back/front and sub control.

 

great, thanks for the insight.

i'm trying to keep the stock head for now because i don't care for the look of the replacement dash kits.

i'll try this set up out and post some pics, thanks!
